Is the innovation in feature size or crafting better circuit architectures? 16nm can help pack more memory in small space which is good but sooner or later we just have to redesign the foundation of transistor to make real progress. After 16nm, maybe 11nm and then we are cut-off with quantum mechanical effects to go lower.

Thanks guys for making me feel old! It seems like not that long ago that I was in the Boise Micron plant watching the boats of wafers float overhead and hearing the brags of the engineers that they were "sub micron".

But I am that old -- I can remember us repairing mask or design defects so we could test by "smushing" traces together or apart with a probe needle viewed through an optical microscope.
